Title: Method of operating a railway hump yard
Inventor: ENNULAT DIETRICH DIPL ING
IPC: B61L17/00
Filed: 1997-02-21
Granted: 1998-05-07
Abstract: The method involves separating a train of carriages (WV) into individual carriage groups (A,B) or carriages (N) according to a separation specification (ZV).

Granted: 1998-09-17
Abstract: Manufacture of painting rollers comprises feeding a thermoplastic carrier roll (2) by a linear moving clamp to a working position in a roll holder where a fibre group (9) forming a flat band is continuously placed around the roll and along the length in 180 deg loops (22) by stepwise roll rotation and simultaneously bonded to the roll surface to form a pile. The multi-stage lay-down of the fibre band (9) involves: a) clamping the fibre band between a pressure blade (16) and winding fingers (18) to form a fibre line that is moved perpendicularly onto the premelted roll (2) surface and pressed in to form a permanent bond; b) releasing the clamp by retracting the pressure blade and moving the winding fingers linearly away from the working position; c) rotating the winding fingers around the roll by an amount equal to several fibre spacings and moving back into the working position just in front of a previously bonded fibre line; d) moving the pressure blades towards the roll surface to form a 180 deg loop in the fibre band and pressing them into the premelted roll surface where they are cut through to form a pile; e) rotating the roll again by a small increment and repeating stages b-d until the entire roll surface is covered.  Also claimed is the process machinery.

Granted: 1999-03-04
Abstract: The invention relates to an absorbent single use hygiene item, comprising a liquid-tight back sheet (4), a liquid-permeable cover sheet (2), an absorbent body (6) containing super-absorbent polymer materials which is suitable for storing bodily fluids, especially urine, and which is located between said back sheet (4) and said cover sheet (2), and a two-layer intermediate part (8) which takes up and distributes liquid. Said intermediate part (8) is made up of a top layer (18) consisting of synthetic fibres and a bottom layer (20), the average pore volume of the top layer (18) being greater than the average pore volume of the bottom layer (20), and is arranged between the absorbent body (6) and the cover sheet (2). The inventive hygiene item is configured in such a way that the bottom layer (20) is made essentially exclusively of chemically cross-linked cellulose fibres and the top layer (18) overlaps the longitudinal ends (21) of the bottom layer with its longitudinal edge sections (19) so that the hygiene item is able to absorb more than one of loss of liquid and give the wearer a feeling of dryness. The cross-linked cellulose fibres of the bottom layer (20) are also more hydrophilic than the synthetic fibres of the top layer (18) of the intermediate part (8).

Title: Motor vehicle seat with upholstered backrest divides backrest crossways into back shell to fold forwards so upper part forms loading surface plus second part as load block between seat top and roof.
Inventor: BUDDENSIEK ANDREAS
IPC: B60N2/30
Filed: 1999-09-27
Granted: 2000-08-31
Abstract: The backrest (4b) can be divided crossways to give a first part (4d) in back shell design which can be folded forwards when inserted horizontally and so forms a loading surface with its rear part as shell has a releasable upholstered second part (4c). The second (4c) blocks off the free space between the upper part of the back (3a) of the seat (3) and the roof (1). This second part can be fixed on the vehicle sidewalls (2) and simply plugged home, clipped in or hung into place with its top part (4f) facing downwards. Thus in the blocking position, the headrest forming part of the seat part (4c) remains on the downwards pointing part (4f) of the seat (4c).
